More than 40,000 websites worldwide have fallen under the spell of a sneaky piece of attack code that silently tries to install malware on the machines of people who visit them, security experts from Websense have warned. The mass attack has been dubbed Beladen because beladen.net is one of the internet domains used to unleash a swarm of exploits that target unpatched vulnerabilities in the Internet Explorer and Firefox browsers and programs such as Apple's QuickTime. It plants highly obfuscated javascript on the bottom of websites that's slightly different each time, making it impossible to spot infected sites using search engines.
